My phone is requesting a PIN/PIN2/PUK/PUK2 code
Your phone is equipped with one or more codes to protect it against unauthorized use. The PIN and PUK codes actually protect the SIM card, a small card inside your phone that establishes the network connection.
In most cases, your operator or service provider is the best source of assistance with PIN and PUK codes.

The most common code is the PIN (Personal Identification Number) code, which you set yourself and can activate and inactivate by following the instructions in your user guide.

The PIN2 code is a PIN code which acts as a second layer of protection for certain features of your phone. It functions in the same way as the PIN code, and more information is available in your user guide.

If the PIN code is entered incorrectly multiple times, your phone may request a PUK (Personal Unblocking Key) code. The PUK code is an 8-digit code provided by your operator or service provider.

If the PIN2 code is entered incorrectly multiple times, your phone may request a PUK2 code.

Please contact your operator or service provider for assistance with your PIN and/or PUK codes. If you have already contacted your service provider and the code provided did not work, you will have to obtain a new SIM card from your operator or service provider.
My phone requests a security code
Your phone is equipped with one or more codes to protect it against unauthorized use. Please note that the security code, which protects the phone itself, differs from the PIN code, which protects the SIM card.
If your phone is prompting you for a security code and you have not activated one, please try the following:

Enter the default security code: 12345. Only try this once.

If your phone still requests a security code, please bring it to the nearest Nokia Care point for inspection. You can find Care point addresses from the drop-down menu to the right.
Please note:

Some operators configure phones so that they only work with their brands' SIM cards. In this case, if you enter the wrong code three or more consecutive times, the phone may lock permanently. If this happens, contact your operator or service provider for assistance.

In other cases when you enter the wrong code three or more consecutive times, the phone switches to a "sleep mode" and does not accept any entries for the next 15 minutes. In this case, power the phone off, then back on, let it sit idle or untouched for 15 minutes, then try again or bring it to a Nokia Care point.

Sorry its a long list , but have included everything.Just pick out what you need...The default security code for Nokia is 12345. SIM pin code:This is a pin code that locks the sim card until you enter the correct code. This protects your account, evenif your sim is put into another handset. To reset it you need the PUK code...Pin Unlock Code (PUK) If you miss keyed (or forget) your SIM PIN code, and enter the wrong one 3-5 times in a row, the sim will lock up, and you'll need to enter the unlock code to release it. You should ask your Network Service Provider for this code when you need it. Don't try to guess it, because after a few wrong guesses, the SIM card will be permanently disabled. The PUK code was printed on the plastic card that your SIM card was attached to. Phone Security Code:This locks the handset, as opposed to the sim card. You can also set some handsets to only accept a "new" sim if the phone security code is entered.Master Reset Code Sometimes known as the Master Code, this allows you to unlock a handset if you have entered the SecurityCode wrongly too many times.Which is the one that you want?

You have to type in security code of your phone in order to log into the phone....By default the security code is 12345 and if you have changed it, you must be knowing....BUT IF YOU WERE NOT ABLE TO GET INTO THE MOBILE WITH THE 12345 OR IF YOU FORGET THE SECURITYCODE, the one and the only way is to flash the mobile phone(ie, reinstalling the firmware), this cant be done by the normal person, u have to take the phone to nearest service center and flash it, they may charge u very minimal amount......

CAUTION: You may loose all the content stored in the phone memory, be careful,but no other way than doing this

PUK code in PIN UNLOCKING CODE, which is required when you give PIN number wrongly for 3 times,This code is OPERATOR specific and not phone specific and you have to call you operator and get PUK if PIN is blocked...

if you provide PUK code wrongly for 7 time, you sim may become useless, then you have to buy new SIM

NOTE: You should ask your service provider,get the PUK, give the PIN 3 times wrongly and it asks for PUk,provide the PUK and set the new PIN..
